Chapter 370 Earth, Fire, Water, Wind, Urgent Mission

"Daoyin, the art of the four sources."

On the panel, this line of words flickered slightly, similar to the discovery of the life seed.

This proves that the discovery this time is of the same level as the discovery of the life seed, or at least not much different. After all, those who can make the panel react must have reached a certain level.

But Han Yi, who stopped, was shocked and confused, because he didn't understand what this sentence meant at all. He had never heard of either 'Daoyin' or 'the art of the four sources'.

At the same time.

Just like when the life seed was discovered, a message was transmitted from the panel. This message was naturally the explanation of 'Daoyin' and 'the art of the four sources'.

The so-called 'Daoyin' is a kind of introduction to the practice of the art of heaven. The art of heaven is superior to the art of immortality. In the immortal world, only the existence of Daozu and above can perform it.

All the arts of heaven need Daoyin to practice. These arts of heaven are like locked cabinets. Only the corresponding Daoyin key can open them.

As for the Four Sources Technique, it is a combination of the four origins of heaven and earth.

Earth, fire, water, and wind.

These four origins of heaven and earth are the basic origins of the world, so they are called the Four Sources Technique.

This explanation was a little brief, and Han Yi still had doubts in his heart, but at this moment, he did not study it in detail. After a slight pause, he turned to the side.

The place where the Four Sources Guide was pointed to by the panel was a shop on the left side.

Han Yi's face was calm. He passed by several stalls on the roadside, looked at them casually, turned to the left, and stepped into this deeper shop.

A rough glance showed that this was not a big shop, with an area of ​​about 300 square meters. For shops in the fairy world, this area is relatively small.

There were not many monks in the shop, only a shopkeeper and four or five monks who were selecting things.

The shopkeeper was an old man wearing black silk clothes. The old man was behind a row of cabinets, with his eyes closed and dozing. His figure was not hunched, but unusually upright.

Han Yi sensed it a little, but he couldn't detect the strength of the old man's breath at all. He couldn't help but feel a chill in his heart. This situation showed that the old man's cultivation was much stronger than his own. His breath was restrained, and even he couldn't detect it.

Han Yi thought about it and thought that if a force could do business in the Immortal Castle, it would be impossible for such a force to send a cultivator of the Transformation Realm to come here casually. At least it would be a semi-immortal, or even a real immortal.

The place where the shop is located is relatively remote. The old man should not be an immortal, that is to say, the other party is a semi-immortal.

Just as Han Yi stepped into the shop, a cultivator had already selected a black jade bottle on the side. There was a viscous spiritual liquid in the bottle.

The cultivator walked to the old shopkeeper with squinting eyes. After the old man opened his eyes, the cultivator asked the price, the old man quoted the price, the cultivator bargained, the old man shook his head, the cultivator bargained, and the old man closed his eyes.

After a while, the cultivator gritted his teeth and still used the old man's price to brush the points.

The old man opened his eyes again, flicked his fingers lightly, and a flash of spiritual light fell on the jade bottle. The invisible restriction on the jade bottle automatically dissipated. The monk who had earned points picked up the jade bottle, his face flashed with joy, put it into the Qiankun Ring, and left quickly.

This is the entire transaction process.

Simple, direct, and efficient.

Han Yi did not look at the direction indicated by the panel, but started from the entrance, looking calmly, browsing one by one.

He found that most of the spiritual objects in this store were objects with strong spiritual light, but in the area below some spiritual objects, there were also some things that looked like ordinary objects, placed casually.

After a while, his sight moved to the bottom of a grid displaying the items for sale. He had already made preparations in his heart before, so there was no extra emotion revealed.

Under this grid, there were seven or eight items without spiritual light. One of the inconspicuous items was a tortoise shell. The tortoise shell was gray and ordinary to the extreme, and there was not even a ray of spiritual light on it.

Next to the tortoise shell, there was another thing without spiritual light, which was a copper coin.

However, the guidance in the panel let Han Yi know that this inconspicuous tortoise shell is the ‘Dao Yin’ of the ‘Four Sources’.

Han Yi continued to browse forward as if nothing had happened. After a round of browsing, he did not hesitate and selected four items. One of them was a sword of the middle-grade magic weapon level. After he broke through the transformation of the spirit, the Guixu sword formation could already accommodate more spiritual swords. Buying this sword was exactly what he needed.

The second item was a rusty copper coin. This copper coin also had no spiritual light, as if it was something from the secular world. Han Yi chose it mainly to cover it up.

The third item was the gray-white tortoise shell, which was the ‘Four Sources Dao Yin’ indicated by the panel.

The rusty copper coin and the gray-white tortoise shell were placed together.

The fourth item was a light blue jade bottle with four words next to it: Tianyi Shenshui. This is a water-attributed spiritual object that contains a strong power of law and is quite popular among the transformation of the spirit cultivators.

Han Yi chose these four items. Among them, the tortoise shell was what he wanted most. The sword and the holy water were also useful to him, and the copper coin was used as a cover.

He walked to the old shopkeeper. The old man opened his eyes and looked at Han Yi as he did in the previous transaction. His eyes were deep.

"Tianyi Holy Water, 3,600 points."

"Qinghong Sword, a medium-grade spiritual treasure, 1,900 points."

"The other two items are all residual spiritual objects collected by our store, each one is 30 points."

"Total, 5,560 points."

After saying this, the shopkeeper said nothing more.

Han Yi was certain that no cultivator had bought things without spiritual light just now. It turned out that these things were the so-called residual spiritual things collected by this shop.

The only trading currency in the shop was the points of the Immortal Castle.

The points system of the Immortal Castle was different from that of the Immortal Court, and the two were not universal.

The points of the Immortal Court were relatively easy to obtain. For example, alchemy and refining, which were all immortal arts, could accumulate a large number of points over time.

And the points of the Immortal Castle, each point must be obtained in three types of tasks, which means that each point contains danger.

As for the use of the points collected in the shops set up in the Immortal Castle, Han Yi did not know, but he had some guesses that it should involve higher-level... immortal tools.

Han Yi did not think much about it, and took out the Immortal Castle token on the spot and traded 5,560 points.

In fact.

This amount of points was considered a large sum of money, and even some peak-level cultivators might not be able to take it out.

Han Yi had 12,000 points, of which 8,300 points were earned by him when he smashed the incomplete mechanical god race when he participated in the regular mission of Sequence 17 ten years ago.

If he hadn't had this chance encounter with the immortal, he wouldn't have been able to get these more than 5,000 points.

He paid quickly, and the old shopkeeper didn't show any other emotions. He flicked his fingers lightly, and the spiritual light fell on the grids on the Qinghong Sword and Tianyi Divine Water, and the invisible spiritual light cover disappeared.

Han Yi took the two spiritual objects without the spiritual light cover, took the tortoise shell and copper coins, put all four of them into the Qiankun Ring, and then turned and walked out of the store.

After leaving the store, Han Yi did not return to the house immediately, but continued to walk deeper.

This trade fair lasted for ten days.

However, three days later, after Han Yi bought another spiritual object, he teleported away and returned to the Shadow Moon node.

What Han Yi didn't know was that the day before he left the Immortal Square node.

A middle-aged-looking Divine Transformation cultivator hurriedly stepped into the remote shop where Han Yi bought the Qinghong Sword, walked directly to the grid on the side, and looked down at the many things placed below.

Most of these things have weak spiritual light, and some even have no spiritual light at all. In the Immortal Castle, these mysterious things with shallow or even no spiritual light and unknown uses are called residual spiritual things.

"Mr. He, what about the residual spiritual things I sold you besides these?" The middle-aged Divine Transformation cultivator asked anxiously.

The shopkeeper glanced at him from the corner of his eye and said calmly: "They are all here. If there are none, they have been sold."

"Sold?" The middle-aged cultivator's tone suddenly rose, and a burst of anger was about to erupt, but when he thought of where he was and who he was facing, he stopped abruptly, his face flushed.

He didn't dare to look up at the half-immortal shopkeeper and fled in a hurry.

"What a pity! The tortoise shell and copper coin obtained from the Extreme Ancient Illusionary Realm must be extraordinary, but they were actually bought."

"I can't afford to offend this half-immortal, so I have to do this."

The cultivator was unwilling, but he could do nothing to the half-immortal shopkeeper, and he didn't even dare to get angry.

And he just found out that the mysterious place he entered by coincidence was called the Extreme Ancient Illusionary Realm.

The Extreme Ancient Illusionary Realm was extremely mysterious and illusory. In the void, only a very small number of cultivators with predestined relationships could enter it. Moreover, after entering, when they come out, they will forget everything in the Extreme Ancient Illusionary Realm, but they can get some spiritual objects from the Extreme Ancient Illusionary Realm.

What this cultivator experienced when he participated in the regular mission before happened to fit the description of the Extreme Ancient Illusionary Realm, but he didn't know it before, so he sold the seemingly ordinary tortoise shells and copper coins, as well as several other residual spiritual objects found in the regular mission, to this shop at a very low price.

Now that it has been bought, it can only be said that he has no fate with the ancient fantasy world. Even if he is unwilling, there is nothing he can do.

After he left, the semi-immortal shopkeeper in the shop flashed through the monks who had bought the residual soul objects bought from this monk during this period of time, and finally stopped on three faces.

These three faces are the ones who have bought the residual soul objects sold to the store by this monk during this period of time. Among them, there is Han Yi after his disguise.

Immediately, he changed his mind and no longer paid attention to this matter. No matter how extraordinary these three residual soul objects are, they have been sold and have nothing to do with him.

On the other side.

After Han Yi was teleported back to the Shadow Moon Node through the space teleportation point, he set up the escape light and returned to the room.

After returning to the quiet room, he took out the five spiritual objects this time.

The middle-grade spiritual treasure, Qinghong Sword, is a long sword with a green body. The long sword is forged with a special refining material called "Qingguang Phoenix Iron". This refining material has the effect of turning into light and is extremely fast, so this sword is named Qinghong Sword, which means "green rainbow light".

Han Yi did not sacrifice it immediately, but threw it directly into the Guixu Sword Formation. It would not be too late to sacrifice it later when he had time.

Tianyi Divine Water is a spiritual object with water attributes. This kind of spiritual object naturally cannot be compared with Wanlingyuan Fire and Zigangxuan Jade Marrow, but it can also be considered precious for the Divine Transformation cultivator. Han Yi intends to condense it into an innate spiritual object in the divine orifice.

Han Yi covered his hand on the light blue jade bottle, and the divine power surged to pull out the divine water. However, this kind of divine water was extremely heavy. Even this small bottle took him half an hour to pull it all out of the jade bottle, wrap it, and send it into the divine orifice in his body.

Then.

Han Yi looked at the copper coin. The copper coin was rusty. On one side was an ancient immortal character "Ru", while on the other side, it was completely erased, leaving only rust.

So far, Han Yi only knew that the name of this copper coin contained the character "Ru", and nothing else was found.

His consciousness fell into the copper coin, and then it disappeared directly.

Weird.

Han Yi was stunned and tried a few more times. In the end, he had no choice but to give up and put it away.

He took out the fourth spiritual object, which was also the spiritual object he bought in the immortal shop later. This was an earth-attributed spiritual object,

called "Earth Spiritual Juice".

This is a relatively common spiritual object. However, according to its grade classification, the one Han Yi bought belongs to the high-grade spiritual juice that can be used for spiritual transformation.

This is also one of the spiritual objects he used to condense the divine orifice. Like Tianyi Divine Water, he wrapped it with divine fire and sent it into the divine orifice.

Of course, the divine orifice where the Purple Gang Xuan Yu Sui, Tian Yi Divine Water and Earth Spiritual Slurry are located is naturally not the first divine orifice, but other core divine orifices.

Then.

Han Yi took out the gray tortoise shell.

Putting the tortoise shell in front of him, Han Yi looked at it carefully.

The tortoise shell is gray, with smooth and neat edges, about one meter long, only half a meter wide, and only a thin layer of thickness, less than a finger wide.

Han Yi also used his divine sense to explore, but found that this tortoise shell, like the copper coin, disappeared when his divine sense fell into it, without any feedback.

He thought of something and called up the panel, but saw that the line of flashing fonts that originally prompted "Dao Yin" on the panel had disappeared.

Instead, two other skills he originally had were flashing slightly.

These two skills were beyond Han Yi's expectations, and made him even more confused.

Wind Wall Technique.

Fire Shield Technique.

"Hmm?"

Han Yi raised his eyebrows, and the explanation of the Four Sources of the Art came to his mind: earth, fire, water, and wind. Among them, earth is also soil, which is also soil, fire, water, and wind.

And his wind wall and fire shield are just 'wind' and 'fire', which are two of the 'four sources'.

With a sudden inspiration, Han Yi gently pointed at the place where the wind wall art that reached the extreme burst out, and the cyan spiritual energy entangled and turned into a thick, like a real defensive wall.

This wind wall twisted and fell towards the tortoise shell, and disappeared in an instant.

Han Yi held his breath.

One breath, two breaths...

Just at the third breath, a cyan spiritual light floated from the tortoise shell, entered his brow at a speed that Han Yi could not react to, and then disappeared.

Han Yi was startled, and cautiously stepped back a few steps, carefully checked again, and found that there was nothing abnormal on his body.

He looked at the panel, but saw that the skill of wind wall in the original panel had disappeared, and a new skill replaced it.

[Four Sources of Taoism: Extreme (1/4)].

Han Yi thought for a moment, and then he used the fire shield again. A flame shield fell into the tortoise shell. Just like before, after three breaths, a flash of fire entered Han Yi's forehead.

On his panel, the fire shield had completely disappeared.

[Four Sources of Taoism: Extreme (2/4)].

However.

What made Han Yi even more confused was that although there was no fire shield and wind wall on the panel, but a new 'Four Sources of Taoism'.

But Han Yi could still cast these two defensive spells.

As for the four sources of Taoism, he had no clue for the time being.

He could only blame it on the fact that the four sources of Taoism had not been gathered.

That is to say, next, he needs to practice two more defensive spells, one earth attribute and one water attribute, and then use this turtle shell to transform it into a corner of the Four Sources Daoist Art, so that this Heavenly Dao Art can be used.

Han Yi's sight moved and fell on another skill on the panel.

[Sword Realm (Completion 1/9)].

Since the Lihuo Sword Art broke through the extreme realm, this mysterious sword art that was originally obtained from the three major sects of Dagan, the Chixiao Sword Sect, has manifested one-ninth of the progress, but it is still a long way from completing the Nine Gates Sword Art.

However.

Han Yi intuitively believed that this Four Sources Daoist Art that could cause the panel to pop up was definitely far beyond this Sword Realm, and the two sides were definitely not at the same level.

Strike while the iron is hot.

Han Yi directly took out two defensive spells from the Qiankun Ring. These were two relatively common spells.

One was called Earth Dragon Art, and the other was called Water Curtain Art.

The main reason why Han Yi chose these two spells was that they were at the same level as the wind wall spell and the fire shield spell. On the other hand, it was naturally because, with his cultivation, he only needed a few thoughts to practice these two spells, and he could reach perfection and even a higher level.

The Four Sources of Magic did not stipulate that these four spells of different attributes needed to be at the same level. Han Yi only needed a few thoughts to practice them to a very high level, and then with the help of the tortoise shell, he could gather the four gates and know what was so magical about this Heavenly Dao spell.

However.

Just as Han Yi took out the two spells, a golden light suddenly appeared on his body, penetrating his body and then soaring into the sky.

The body of the golden light was his fairy castle token.

At this moment, the golden light flashed rapidly.

At the same time, a huge bell sounded from outside, deafening, and rang seven times in a row, and Han Yi's face changed drastically.

"The golden token flashed quickly, and the fairy bell rang seven times."

"It's an urgent task."
